Further comprises a storage cylinder 200, a polishing pipe 201, a polishing sheet 202, a material guiding port 203, a plugging plug 204 and an annular bag 205; the cartridge 200 is mounted on the base plate 100; the polishing pipe 201 is detachably mounted on the storage barrel 200, and the polishing pipe 201 is formed by splicing two detachable half pipes, so that the subsequent polishing sheets 202 are convenient to mount and replace; wherein, the inner cavity of the polishing tube 201 is columnar and conical, the columnar inner cavity forms an opening towards the top end of the polishing tube 201, and the inner diameter of the conical inner cavity gradually decreases from top to bottom; the polishing sheet 202 is arranged at the conical inner cavity part of the polishing pipe 201 through a mounting groove (not numbered in the figure), and meanwhile, the back end of the polishing sheet 202 is provided with a plurality of bulges and forms a splicing limit (not shown in the figure) with the inner wall of the polishing pipe 201 so as to prevent the polishing sheet 202 from rotating in the mounting groove; the material guide opening 203 is arranged at the bottom end of the polishing pipe 201, and the polishing pipe 201 and the storage cylinder 200 are communicated through the material guide opening 203; the sealing plug 204 is arranged in the polishing pipe 201, the diameter of the sealing plug 204 is consistent with the inner diameter of the material guiding opening 203, and the sealing plug 204 can reciprocate along the vertical direction and form sealing for the material guiding opening 203 when the pin shaft workpiece 105 is processed; the annular bag 205 is arranged at the top end of the polishing pipe 201, can expand after the head of the pin shaft workpiece 105 is inserted into the polishing pipe 201, and can form a seal on the top opening of the polishing pipe 201;
In operation, as shown in fig. 2, 3,4, 8 and 9, the electric push rod 102 drives the motor 103, the clamp 104 and the pin shaft workpiece 105 to move downwards, and the pin shaft workpiece 105 is inserted into the polishing pipe 201, and along with the downward movement of the pin shaft workpiece 105, the pin shaft workpiece 105 can squeeze and push the sealing plug 204 to move downwards, and the material guide opening 203 is sealed by the sealing plug 204, at this time, the annular bag 205 can expand radially and seal the top opening of the polishing pipe 201, and the inner ring surface of the annular bag 205 can be attached to the side surface of the pin shaft workpiece 105, so that an approximately sealed polishing space is formed inside the polishing pipe 201; meanwhile, the motor 103 acts and drives the pin shaft workpiece 105 to rotate, and the head edge of the rotating pin shaft workpiece 105 gradually contacts with the polishing surface of the polishing sheet 202 under the pushing of the electric push rod 102, so that polishing or chamfering treatment of the head edge of the pin shaft workpiece 105 is formed;
Meanwhile, dust and debris impurities generated by polishing can be temporarily stored in a closed space formed by the annular bag 205, the polishing pipe 201 and the plugging plug 204, so that the problems of dust and waste diffusion and pollution to the processing environment in the polishing process are solved; after the pin shaft workpiece 105 is processed, the motor 103 stops rotating, the output shaft of the electric push rod 102 contracts and moves out of the polishing pipe 201 on the pin shaft workpiece 105, the blocking plug 204 gradually loses blocking of the material guiding opening 203, dust and debris impurities can fall into the storage barrel 200 from the material guiding opening 203 to be collected as shown in fig. 3, and the problems that the debris and the waste are scattered on a machine table and the collection difficulty is high are solved.
Referring to fig. 3 and 8, the stopper 204 is reciprocally movable in a vertical direction in order to achieve the closing; to this end, a cylinder 206 is installed inside the storage cylinder 200; a slide bar 206a is connected inside the cylinder 206 in a sliding manner; one end of a sliding rod 206a positioned in the cylinder 206 is rotatably provided with a piston plate 206b; the interior of the barrel 206 is also provided with a spring 206c, with the spring 206c being located below the piston plate 206b; wherein, one end of the sliding rod 206a far away from the piston plate 206b passes through the material guiding opening 203 and is fixedly connected with the plugging plug 204;
During operation, the electric push rod 102 drives the pin shaft workpiece 105 to move downwards, and the end face of the head of the pin shaft workpiece 105 contacts and presses the top end of the plugging plug 204, so that the plugging plug 204, the slide rod 206a and the piston plate 206b are pushed to move downwards and the pressing spring 206c is contracted; conversely, when the electric push rod 102 drives the pin shaft workpiece 105 to move upwards, the piston plate 206b, the slide rod 206a and the plugging plug 204 can be moved upwards through the spring 206c, so that the upward movement reset of the plugging plug 204 is realized; that is, the movement of the closing plug 204 to and fro in the vertical direction is realized.
Referring to fig. 3 and 8, in order to achieve inflation/deflation of annular balloon 205; for this, a gas storage chamber 207 is formed between the piston plate 206b and the bottom of the cylinder 206; the middle part of the bottom end of the cylinder 206 is communicated with the annular bag 205 through a hose;
When the device works, on the basis that the plugging plug 204 moves downwards (namely, the pin shaft workpiece 105 moves downwards to the polishing pipe 201 for processing), the plugging plug 204 can drive the sliding rod 206a and the piston plate 206b to move downwards, so that gas in the gas storage cavity 207 is gradually extruded into the annular bag 205 through a hose, and as the annular bag 205 is also provided with a shielding plate (not numbered in the figure), radial expansion is formed after the gas in the annular bag 205 is increased, namely, after the pin shaft workpiece 105 moves to a specified position, the annular bag 205 is expanded to the maximum state and is wrapped outside the pin shaft workpiece 105 (because the contact surface between the annular bag 205 and the pin shaft workpiece 105 is not large, the surface of the pin shaft workpiece 105 is smooth, and the friction force between the pin shaft workpiece 105 and the annular bag 205 can be ignored when the pin shaft workpiece 105 rotates); on the contrary, after the machining is completed, in the process of moving up and moving out the polishing pipe 201 of the pin shaft workpiece 105, the spring 206c gradually resets and pushes the piston plate 206b to move up in the cylinder 206, so that the gas in the annular bag 205 is pumped into the gas storage cavity 207 again, and the annular bag 205 resets to the initial state;
notably, the shrinkage (initial state) of annular bladder 205 may facilitate insertion of unground pin shaft workpiece 105 into grinding tube 201 through the middle of annular bladder 205 (the edges of the head of unground pin shaft workpiece 105 are relatively sharp, which may scratch annular bladder 205); the expansion of the annular bladder 205 and the attachment of the surface of the pin work piece 105 can seal the top opening of the grinding tube 201, and can prevent the diffusion of grinding dust without affecting the rotation grinding of the pin work piece 105.
Referring to fig. 3, 8, 9, 10, 5, 6 and 7, in order to reduce the temperature of the polished sheet 202 after polishing; for this purpose, the inner wall of the polishing pipe 201 is provided with a cooling groove 208a located outside the polishing sheet 202, and a plurality of protrusions (not shown) for abutting against and supporting the polishing sheet 202 are provided in the cooling groove 208 a; the bottom of the polishing pipe 201 is also provided with a communication hole 208b for communicating the cooling groove 208a with the inside of the storage cylinder 200; cooling water is injected into the storage cartridge 200; a liquid storage cavity 208 is formed between the piston plate 206b and the top of the cylinder 206; the top of the cylinder 206 is communicated with a one-way liquid inlet valve pipe and a one-way liquid outlet valve pipe (neither reference sign in the figure); the inlet of the one-way liquid inlet valve pipe is positioned below the liquid level of the cooling water, a filter ball (not numbered in the figure) for filtering fine impurities is arranged at the inlet, and the outlet of the one-way liquid outlet valve pipe is communicated with the cooling groove 208 a;
When the device works, as shown in fig. 8, on the basis that the pin shaft workpiece 105 pushes the sealing plug 204 to move downwards (namely, the pin shaft workpiece 105 moves downwards into the polishing pipe 201 for processing), the sealing plug 204 can drive the sliding rod 206a and the piston plate 206b to move downwards and compress the spring 206c, and in the process, the device can be used through a one-way liquid inlet valve pipe at the left side of the top of the cylinder 206 to pump cooling water in the storage cylinder 200 into a liquid storage cavity 208 of the cylinder 206;
After the pin shaft workpiece 105 and the polishing sheet 202 are polished, the high temperature generated by the polishing sheet 202 is difficult to dissipate; therefore, in the process of moving up the pin shaft workpiece 105 after polishing, as shown in fig. 3, the compressed spring 206c rebounds to push the sealing plug 204, the sliding rod 206a and the piston plate 206b to move up, in this process, cooling water in the liquid storage cavity 208 in the cylinder 206 can be output into the cooling tank 208a through the one-way liquid outlet valve pipe, as shown in fig. 9, then liquid in the cooling tank 208a can be discharged from the communication hole 208b and falls into the storage barrel 200, and in the whole process, the cooling water circulates in the cooling tank 208a to contact and exchange heat with the polishing sheet 202, so that the temperature of the polishing sheet 202 is reduced, the service life of the polishing sheet 202 is prolonged, and the polishing quality of the next workpiece is improved;
As shown in fig. 8 and 9, the cooling water discharged from the communication hole 208b has a relatively high temperature (water after heat exchange with the polishing sheet 202), and natural cooling of the liquid is possible from top to bottom.
